The arrival of Brandon Marshall in Miami is sure to help the Dolphins' passing game in 2010, but will the Dolphins give Marshall the same boost in value?

Marshall comes over from Denver, where he hauled in 101 receptions last season as the unquestioned No. 1 target, including an NFL-record 21 in Week 14. He'll immediately take over as Miami's go-to receiver, but there are a few things to consider before assuming Marshall is ready to vault into the elite WR stratosphere.

Marshall has been and likely always will be a character concern. He was a suspension risk in quiet Denver, and the move to South Beach has to have fantasy owners nervous about whether he can handle the extra off-field distractions. Injuries have also been a concern for Marshall, who underwent minor hip surgery this offseason, his second in about 14 months. Also, there's more receiver competition in Miami, something Marshall didn't have to deal with in Denver. QB Chad Henne is still unproven and the Dolphins are a run-heavy team that hasn't had a 1,000-yard receiver since Chris Chambers in '05.

As a result, Marshall's ceiling will be somewhat limited in Miami. He's still a top-10 receiver in our preseason rankings (No. 8), but there are too many questions and risks surrounding him to recommend him as a top-five WR option.

Marshall's move to Miami will have more of a positive impact on Henne than anyone by giving him a true No. 1 receiver. Don't hesitate to target Henne as a QB2. Meanwhile, expect Marshall to overshadow Brian Hartline, Davone Bess and Greg Camarillo in the passing game, leaving them to fight for scraps behind him. Even lightly-used Anthony Fasano could suffer with the 6-4 Marshall providing a big target in the red zone.

Marshall is set up to have a great season in Miami if he can just stay healthy and out of Bill Parcells' doghouse.
